arms. 5 is provided at its rear end with a gear segment 6, and the lever7 is provided with a sleeve 8, which is adapted to be fixed to the baradjacent to the rear end of that arm 4 which carries the gear segment 6.The lever 7 is provided with a pawl 9, which is adapted to engage theteeth of the segment 6.

The wheels 10 are loosely journaled upon the intermediate portion of thebar 1, and are held against lateral movement thereon by the adjacentteeth 2, mounted upon the said bar. The wheels 10 are provided at theiropposite sides with the frusto-conical portions 11, which materiallyincrease the transverse thickness of the said wheels and constitute, attheir outer faces, bearing surfaces adapted to engage the adjacent teethto the said wheels which are carried by the bar 1.

By such an arrangement it will be observed that by swinging the lever 7the teeth 2 may be caused to operate at a greater or less degree belowthe surface of the ground, or the said lever 7 may be swung so that thepointed ends of the teeth 2 will be upwardly disposed, and all portionsof the teeth will be elevated above the surface of the ground. It willalso be seen that, by removing the intermediate teeth 2 of the bar 1,the wheels 10 may be shifted laterally longitudinally of the bar, and,by reinserting the said teeth in their respective perforations, the saidwheels will be held in adjusted positions upon the bar. It will also beseen that, by removing adj a- Be it known that I, BENJAMIN F. LUKE, acitizen of the United States, residing at Orangeville, in the countyEmery and State of Utah, have invented a new and useful Implements, ofwhich the following is a speci attachment for agriculturalimplements,and

and described. p Primarily the attachment is designed to be applied to asoil pulverizer or compactor, as,

soil for. cultivating purposes.

The object of the invention is to provide which comprises a bar havingdetachable harrow teeth mounted thereon and supporting wheels journaledthereon and which are means of the said harrow teeth. Arms provided withbearings receive the end. portions of thesaid bar and are adapted to beconnected with the implement to which the attachment is applied, andmeans is provided upon one of the said arms for swinging the bar,whereby the harrow teeth may be elevated or lowered as desired. 1

In the accompanying drawings :Figure l ally along the longitudinaldimension of the bar 1. The advantage gained by providing meansrforadjustably positioning the arms and the wheels upon the said bar is thatthe arms may be spread sufliciently to be connected with the frame ofthe implement at desired points, and also the wheels 10 may be spacedapart so as to follow plows or soilopeners carried by the implement, theWheels being of such configuration as to follow in the furrows andprevent the teeth carried by the bar 1 from casting the soil into thesaid furrows. At the same time the said wheels will compact the sides ofthe said furrows, and leave the same in proper condition for thereception of seed or the flowing of water therein.

Having described my invention, what I claim as new, and desire tosecure, by Letters Patent, is

1. A bar, teeth carried by the bar, suptransverse sectional view of aportion of the attachment. Fig. 4 is a transverse sectional view of aportion of the attachment, showing a pawl and gear segment used thereon.The attachment consists of a bar 1, which is preferably in the form of apipe, and at suitable intervals upon the same are secured the harrowteeth 2, the shanks of which pass transversely through the said bar andare secured by means of the nuts 3 screw-threaded upon the end portionsof the said shanks of the teeth. The arms 4 are adapted to be connectedat their forward ends with the frame of an'agricultural implement suchas above.

with the bearings 5, in which the end por- Eorting wheels adjustablymounted upon the ar, said teeth forming means for retaining the wheelsin adjusted position.

2. A bar, teeth carried by the bar, supporting wheels journaled on thebar, arms having bearings which receive the bar, one of the arms havinga segment, and a lever at tached to the bar and carrying a pawl forengagement with the segment.

3. A bar, teeth carried by the bar, supporting wheels journaled on thebar, arms having bearings which receive the bar, and means for turningthe bar in the bearings of the arms.

4. A bar, teeth carried by the bar, supporting wheels journaled on thebar, arms having bearings which receive the bar and which lie betweenadjacent teeth, said teeth forming means for retaining the bearingsagainst longitudinal movement on the bar.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
